Description

Device for packaging and dispensing a product with improved sealing between two containers

The present invention relates to the general field of containers for packaging and dispensing liquid or semi-liquid products, such as cosmetic products (such as hair products), and more particularly to hair care products, such as hair care essences, hair dyes, hair oils, hair creams, or to products for cleansing, such as body washes, or to skin care products, such as body milks or creams, cleansing products, or to any product for hair care or skin care.

An advantageous application of the invention is the use of the device for packaging cosmetic products, such as cosmetic products for dyeing human keratin fibres. Other advantageous applications of the invention may be the use of containers for storing care products, adhesive products, polymer paints, flavourings liquids, etc.

The expression "cosmetic product" is understood to mean a product as defined in article 2 of regulation No. 1223/2009 of the european parliament and council of europe, 11 and 30 months 2009.

More particularly, the present invention relates to a packaging and dispensing device having an upper container mounted on a lower container having a neck.

Typically, the upper container comprises a sealing lip in radial contact with the end of the neck of the lower container.

However, during transport of the lower container, the end of the neck may be damaged, resulting in a change of the seal between the two containers. In particular, during transport in an assembly line, the lower container may be gripped and rotated by its neck in an unstable machine, and this may cause damage on the neck of the lower container and may cause a change in the seal between the two containers when the upper container is assembled on the lower container.

It is an object of the present invention to provide a device for packaging at least one product which is simple in construction, easy to manufacture and which has a good gas tightness between the lower container and the dispensing member.

It is an object of the present invention to provide a device for packaging at least one product and dispensing at least said product onto a surface, the device comprising at least one container defining a product chamber containing said at least one product and a dispensing member mounted on the at least one container and having a first dispensing orifice in fluid communication with the product chamber.

The lower container has a neck that allows access to the product chamber. The dispensing member includes a dispensing conduit in fluid communication with a product cavity, an assembly skirt radially surrounding the dispensing conduit, and an annular sealing lip radially disposed between the dispensing conduit and the assembly skirt.

The annular sealing lip is configured to radially abut a sealing portion of a neck of a container.

The sealing portion is positioned axially away from the open end of the neck.

The open end of the neck is the free end of the neck that allows access to the product chamber.

Thus, the sealing portion is not subject to degradation when the container is carried by its neck and/or when the dispensing member is assembled on the container, and thus the seal between the dispensing member and the container is effective.

Furthermore, the open end of the neck is configured to guide the dispensing member into the container, thereby facilitating assembly of the dispensing member on the container.

In an embodiment, the annular sealing lip radially bears against an inner surface of the sealing portion of the neck.

Advantageously, the sealing portion of the neck is a portion extending radially inwardly from an inner surface of the upper portion of the neck. Advantageously, the radially inwardly extending portion of the neck extends at the same axial height as the annular groove formed on the outer surface of the neck.

The inner diameter of the sealing portion of the neck may be smaller than the outer diameter of the sealing lip of the dispensing member.

Advantageously, the sealing portion of the neck is configured to deform elastically when the dispensing conduit of the dispensing member is inserted into the neck of the at least one container.

In other words, for example, when inserting the dispensing conduit into the neck of the container, the sealing portion of the neck can thus be deformed under slight induction, depending on the material used and/or its dimensions, and return to its initial position when no induction is exerted on the sealing portion.

Advantageously, the annular sealing lip of the dispensing member is configured to be elastically deformed in a radial direction against a sealing portion of the neck upon insertion of the dispensing conduit of the dispensing member into the neck of the at least one container.

The width of the sealing portion of the neck may be thinner than the width of the open end of the neck.

For example, the sealing portion of the neck has a C-shaped cross-section.

Such a specific shape increases the radial interference between the sealing portion and the sealing lip. Thus improving the airtightness of the device.

For example, an assembly skirt radially surrounds the neck of the container and cooperates with said neck to axially fix the dispensing member on the container.

The assembly skirt may be provided on its radially inner surface with an annular rim which cooperates with an annular groove of the container by means of a snap-fit attachment, so that the dispensing member is axially retained relative to the container while allowing rotational movement of one relative to the other.

Said annular groove of the container may be axially arranged between two outer annular shoulders, and the sealing portion of the neck is axially above the upper annular shoulder.

The dispensing member for example defines a second container delimiting a second product chamber containing a second product and separated from the first product chamber, said containers being able to rotate one with respect to the other without axial movement.

In an embodiment, the device further comprises a temporary closure member configured to close the open end of the second container before the first use and comprising a cylindrical skirt surrounding said open end and a plug connected to said cylindrical skirt, said cylindrical skirt being provided on its cylindrical inner surface with an internal thread cooperating with an external thread provided on the upper container and being provided on its cylindrical outer surface with first anti-rotation means cooperating with second anti-rotation means provided on the lower container for preventing rotation between the closure member and the lower container. The closure member is free of any member that is axially retained with both containers such that when the upper container is rotated in a first rotational direction, the closure member translates downward until falling into the first product chamber.

Advantageously, the upper surface of the plug comprises: a first annular sealing lip extending axially towards the second container and having an outer diameter substantially equal to the inner diameter of the open end of the dispensing conduit; and a second sealing lip extending axially in an annular groove provided at an end of the lower open end.

The first sealing lip is inserted into the dispensing conduit and is configured to close it in a sealing manner.

The second sealing lip improves the air tightness of the upper container.

For example, the second sealing lip is annular.

The axial length of the second sealing lip may be less than the axial length of the first sealing lip.

The invention will be better understood by studying the detailed description of an embodiment considered by way of non-limiting example and illustrated in the accompanying drawings, in which:

Fig. 1 to 11 show an example of a device for individually packaging two products and dispensing a mixture M of these two products at first use, which device is designated by the general reference numeral 10.

The device 10 may be used for packaging two cosmetic products a and B, for example two liquid or semi-liquid cosmetic products, or a liquid product and a powder. For example, the product may be a hair care product, such as a hair care product, e.g. a hair dye, a hair cream or any product for hair. However, packaging and distribution of other types of products may be provided. The device 10 is suitable for a single application product. By way of example, the first product a is an oxidizing colorant and the second product is an oxidizing agent B, which when mixed together to make the mixture M form a hair coloring agent.

The device 10 may also be used to package other types of cosmetic products (such as skin care products), or other types of products (such as flavored liquids) such as food products, or any product that may be stored separately during transport and storage (such as adhesive products, polymer coatings, etc.).

However, the device 10 may also be used to package and dispense only a single product.

The device 10 extends along a longitudinal axis X-X', which is assumed to be vertical on the drawings. The device 10 comprises a lower container 12 and an upper container 14, which can rotate one with respect to the other about said longitudinal axis X-X'.

When used for packaging and dispensing only one product, the device may include only the upper container 14 and not the lower container 12, or two containers, but the upper container functions as the dispensing member.

The lower container 12 has the shape of a bottle with an elongated body along a longitudinal axis provided with: a closed lower end 16 forming a bottom, and an upper end 18 forming a neck provided with an opening 20, opposite the lower end 16, allowing access to an inner cavity 22 containing the first product a.

In the illustrated embodiment, the neck 18 has an outer diameter smaller than the outer diameter of the body of the lower container 12 and comprises, on its outer surface, two outer annular shoulders 18a delimiting an annular groove 18 b. The body of the lower container 12 may be made of, for example, a rigid plastic material.

The upper container 14 is in the form of a lid and comprises a central dispensing duct or duct 24 containing the second product B, having an upper portion shaped: having a dispensing closure 26 and a lower end of the inner cavity 24a provided with an opening 28, opposite the dispensing closure 26, and allowing access to the duct 24 containing the second product B.

The dispensing closure 26 is designed to be broken upon first use to open the dispensing orifice 24b in flow communication with the internal cavity 24 a.

In the embodiment shown in fig. 1-10, dispensing closure 26 is frangible. Alternatively, the dispensing closure 26 may be unscrewed or torn or peeled off from the conduit 24.

As shown, the end of the conduit 24 is provided with a notch 26a to easily separate the dispensing closure 26 from the conduit 24. A plurality of notches 26a may be positioned circumferentially around the conduit 24 and spaced apart from one another. Alternatively, a single notch 26a may be provided around the conduit 24.

The dispensing closure 26 may be provided with a plug (not shown) opposite the recess 26a, which is designed to be inserted into the dispensing orifice 24b after the dispensing closure 26 is disconnected from the conduit 24. The dispensing closure 26 is thus repositionable and can close the dispensing orifice after use.

The dispensing conduit 24 is surrounded by an assembly skirt 30, which is provided on its radially inner surface with an annular rim 30a, which cooperates, by means of a snap-fit attachment, with the annular groove 18b of the lower container 12, so that the upper container 14 is axially retained with respect to the lower container 12, while allowing rotational movement of one with respect to the other.

The upper container 14 has an annular sealing lip 32 extending substantially along the longitudinal axis X-X' downwards into the annular channel 14a formed between the dispensing duct 24 and the assembly skirt 30. Sealing lip 32 is annular and bears tightly against the radially inner surface of portion 18c of neck 18, which is annular, so as to provide a seal between lower container 12 and upper container 14.

Advantageously, the annular sealing lip 32 of the upper container 14 is configured to elastically deform in a radial direction against the sealing portion 18c of the neck 18 when the dispensing duct 24 of the upper container 14 is inserted in the neck 18 of the lower container 12.

In particular, the sealing portion 18c of the neck 18 comprises a chamfer extending inwards in a radial direction from the upper portion 18d of the neck, which contributes to the elastic deformation of the annular sealing lip 32 of the upper container 14 when it is assembled on the lower container 12.

Advantageously, the inner diameter of the upper portion 18d of the neck 18 of the lower container 12 is greater than the outer diameter of the annular sealing lip 32 of the upper container 14. Thus, the open end of the neck 18 of the lower container 12 and the annular sealing lip 32 are less likely to be damaged by contact with each other when the upper container 14 is assembled on the lower container 12.

The sealing portion 18c is located axially away from the open end of the neck 18 and, therefore, is not subject to degradation when the lower container is carried by its neck and/or when the upper container 14 is assembled on the lower container 12.

The sealing portion 18C has a C-shaped cross-section, which allows said sealing portion 18C to be elastically deformed when the dispensing duct 24 of the upper container 14 is inserted into the neck 18 of the lower container 12. This particular shape increases the radial interference between the sealing portion 18c and the sealing lip 32. The airtightness of the device 10 is thus improved.

The upper portion 18d of the neck 18 is configured to guide the upper container 14 until the assembly skirt 30 of the dispensing tube 24 mates with the lower container 12 by a snap-fit attachment.

As shown, the upper container 14 further includes an application member 40 mounted on the distribution pipe 24 and including a cover 42 mounted on an upper end of the distribution pipe 24 and a plurality of application teeth 44 extending outwardly from the cover 42.

The cover 42 includes an opening 42a for dispensing the closure 26.

By way of non-limiting example, the application member 40 comprises four

rows

44a, 44b, 44c, 44d of application teeth 44, each row of application teeth being inclined towards the flow path of the product to be dispensed.

Alternatively, the application member 40 may include only two rows of application teeth 44 or more than four rows of application teeth.

All of the teeth 44 are inclined towards the central longitudinal axis X-X' of the device 10.

Each tooth 44 has a base section connected to the cover 42 and a free end opposite the base section.

Each tooth 44 is resiliently deformable and is able to flex about its junction with its base section and the cover 42.

In other words, the teeth are thus able to deform under slight inducement applied by the user, for example by the dispensing closure 26, or during application on an application surface (such as hair and/or scalp), due to the materials used and/or their dimensions, and return to their original position when no inducement is applied on the teeth.

As illustrated in fig. 1-3, during shipping and prior to first use, the dispensing orifice 24b of the upper container 14 is closed by the dispensing closure 26 located between the applicator teeth 44. Thus, the rows of the plurality of teeth 44 are arranged two by two on each side of the dispensing closure 26. The

rows

44a, 44b, 44c, 44d of the plurality of teeth 44 are parallel to each other.

As shown in fig. 5, two adjacent rows of

teeth

44a, 44 b; 44c, 44d are staggered in such a way that their free ends form only two rows of teeth 44 when four rows are pushed towards the axis X-X' of the dispensing orifice 24 b. In other words, when the rows of teeth are oriented towards the axis X-X' of the dispensing orifice 24b, the free ends of the teeth 44 of the first row 44a fit between the free ends of the teeth 44 of the second row 44b, and the free ends of the teeth 44 of the third row 44c fit between the free ends of the teeth 44 of the fourth row 44 d.

During transport and prior to first use, when dispensing closure 26 is located between teeth 44, teeth 44 of second row 44b and fourth row 44d of teeth are mechanically stressed in a first position in which teeth 44 in contact with dispensing closure 26 form a first angle α 1 with the longitudinal axis.

When the dispensing closure 26 is removed, the teeth 42 of the second 44b and fourth 44d rows of teeth, which are in contact with the dispensing closure 26, automatically flex in a second position corresponding to the rest position of the teeth. In the rest position, the teeth of the second and

fourth rows

44b, 44d of teeth form a second angle α 2 with the longitudinal axis. The second angle is greater than the first angle.

In this rest position, the free ends of the teeth of the second and

fourth rows

44b, 44d of teeth are in the flow path of the product to be dispensed.

The elastically deformable sloping teeth 44 allow a good retention and recovery of the product to be dispensed. In fact, the distribution of the product is easily controlled by the inclined teeth 44.

Furthermore, the staggered arrangement of the teeth 44 allows a zigzag distribution of the products to be dispensed.

Each tooth 44 has a triangular cross-section. The cross-section of each tooth may continuously decrease over at least a portion of its length towards its free end.

As shown, the application teeth extend transversely beyond the first dispensing orifice, and the teeth have the shape of straight bars.

The free ends of the teeth are not in contact in the rest position.

The teeth 44 are made of a flexibly deformable and resilient material, such as a thermoplastic, e.g. Low Density Polyethylene (LDPE), High Density Polyethylene (HDPE), thermoplastic elastomer (TPE), Thermoplastic Polyurethane (TPU) or any material capable of elastic deformation.

The cover 42 and/or the upper container 14 may be made of a thermoplastic polymer, such as polypropylene (PP), Acrylonitrile Butadiene Styrene (ABS), polyethylene terephthalate (PET), nylon, or any material that is harder than the teeth 44.

As illustrated in fig. 2 and 3, the temporary closure member 50 is during transport and prior to first use. In the illustrated example, the closure member 50 is a cap that can be screwed in a sealed manner onto an external thread 28a provided on the outer surface of the lower end 28 of the dispensing duct 24, between the dispensing duct 24 and the inner surface of the neck 18.

The closure member 50 includes a cylindrical skirt 52 and a plug 54 connected to the skirt 52. A cylindrical skirt 52 extends radially between the neck 18 of the lower container 12 and the lower end 28 of the dispensing conduit 24 of the upper container 14.

The cylindrical skirt 52 is provided on its cylindrical inner surface with internal threads 42a which cooperate with the external threads 28a of the distribution pipe 24.

The cylindrical skirt 52 is further provided on its cylindrical outer surface with outer longitudinal ribs 52b regularly spaced over the entire circumference of the cylindrical skirt 52. The outer longitudinal rib 52b cooperates with an inner longitudinal rib 18e provided on the inner circumferential surface of the neck portion 18 such that the closure member 50 is prevented from rotating relative to the lower container 12.

As shown and in the non-limiting example, the outer longitudinal rib 52b extends axially beyond the upper surface of the cylindrical skirt 52.

In the illustrated example, the plug 54 has an outer diameter that is greater than the outer diameter of the open end 28 of the dispensing conduit 24.

The cylindrical skirt 52 and the lower container 12 may be provided with anti-rotation means shaped differently from the longitudinal ribs. Generally, the cylindrical skirt 52 and the lower container 12 are provided with anti-rotation means for preventing the closure member 50 from rotating relative to the lower container 12.

The upper surface of the plug 54 comprises a first annular sealing lip 54a extending axially towards the upper container 14 and having an outer diameter substantially equal to the inner diameter of the lower open end 28 of the dispensing duct 24, so as to be inserted into said dispensing duct 24 and close it in a sealed manner.

The upper surface of the plug 54 includes a second sealing lip 54b that extends axially in an annular groove 28b provided at the end of the lower open end 28.

The second sealing lip 54b may be annular.

The addition of a second sealing lip improves the gas tightness of the upper container 14.

As shown, the axial length of the second seal lip 54b is less than the axial length of the first seal lip 54 a.

The plug 54 is connected to the cylindrical skirt 52 by a bridge 54c of hinge-forming material and by a connector or coupling 54d of frangible material. In the embodiment shown in the drawings, there are seven connections 54d of frangible material regularly spaced around the circumference of the plug 54. A number of frangible connections 54d other than seven may be provided. For example, the plug 54 is connected to the cylindrical skirt 52 by a bridge 54c of hinge-forming material and by at least one frangible connection 54 d.

As shown, the plug 54 includes a plurality of axially projecting strips or blocks 54e disposed on a lower surface of the plug 54 opposite an upper surface of the plug 54 having

annular sealing lips

54a, 54 b. The axially protruding pieces 54e are circumferentially provided on the lower surface of the plug 54 and are regularly spaced from each other.

As shown in fig. 9, there are four blocks 44 e. However, the number of blocks 54e is not limited to four, and may be, for example, equal to one, two, or three or higher than four.

The block 54e is disposed on a diameter of the plug 54 that is substantially equal to the diameter of the dispensing conduit 24 such that the block 54e avoids blocking the open lower end 28 of the dispensing conduit 24 when the closure member 50 is dropped into the lower container 12.

Closure members without axially projecting blocks 54e and/or without frangible connections 54d and bridges 54c may also be provided.

In a non-limiting example, the first rotational direction may be a clockwise or counterclockwise direction.

The device 10 is assembled as follows.

The upper container 14 is filled with the second product B and the closure member 50 is screwed onto the dispensing duct 24 until the plug 54 axially abuts the open end 28 of said dispensing duct 24.

The upper container 14 is fitted, by a simple translational movement along the longitudinal axis X-X', onto the lower container 12 which has been previously filled with the first product a until the assembly skirt 30 of the upper container 14 is snap-fastened onto the neck 18 of the lower container 12.

To place the interior volume 24a of the upper container 14 in flow communication with the interior volume 22 of the lower container 12 when the device 10 is first used, a user rotates the upper container 14 relative to the lower container 12 in a first rotational direction F1 (shown in fig. 10), causing the closure member 50 to translate downwardly along the longitudinal axis X-X' as compared to the lower container 12 until falling into the interior volume 22 of the lower container 12.

As illustrated in fig. 10 and in a non-limiting example, the first rotational direction F1 is a counterclockwise direction. The first rotational direction may also be clockwise.

In this embodiment, once the closure member 50 is in the internal volume 22 of the lower container 12, it acts as an agitation member for the mixture M comprising the first product a and the second product B by the twisting and shaking movement of the device 10.

The user then breaks the frangible dispensing closure 26 in order to use the device 10 and dispense the resulting mixture M contained in the lower container 12 through the dispensing conduit 24 and dispensing orifice 24 b.

The lower container 12 may be processed by an injection blow molding process. The lower container 12 is made of, for example, a polymer material, such as a thermoplastic material. The lower container 12 is, for example, injection molded onto a preform core consisting of a container neck to which a thick tube of polymeric material is attached. The preform core has longitudinal outer ribs which, when compressed air is filled into the preform to expand the thick tube into the bottle shape of the lower container, will form anti-rotation longitudinal ribs 18e provided on the inner circumferential surface of the neck 18.

Thus, the longitudinal anti-rotation ribs 18e are directly manufactured during the injection blow molding process of the lower container 12.

When a user rotates the upper container in a second rotational direction F2 (shown in fig. 12), the closure member 50 translates upward until the frangible connection 54c is broken by a force, causing the plug 54 to pivot about the bridge 54B of hinge-forming material and the second product B to flow toward the interior cavity 22 of the lower container 12.

As illustrated in fig. 12 and in a non-limiting example, the second rotational direction F2 is a clockwise direction. The second rotational direction F2 may also be counterclockwise as viewed in fig. 10.

The user may further rotate the upper container 14 in a rotational direction opposite the second rotational direction F2 to translate the closure member 50 downward until falling into the interior cavity 22 of the lower container 12. (not shown in the drawings)

In this embodiment, the user may open the dispensing conduit 24 by rotating the upper container 14 in both rotational directions.

When the device 10 is in use, with the closure member 50 in front of the open lower end 28 of the dispensing conduit 24, said closure member 50 will abut against said lower end 28 by means of its block 54e, thus allowing the mixture M contained in the lower container 12 to flow between the blocks 54e in the upper container 14 when said device 10 is turned upside down.

The embodiment shown in fig. 13, in which like elements have like reference numerals, differs from the embodiment of fig. 1 to 12 only in the shape of the dispensing closure.

As illustrated in fig. 13, the dispensing closure 60 is configured to close the dispensing orifice 24b and includes an operating element 62 having a grip 62a and a body 62b extending from the grip 62 a. As illustrated, the body 62b is tubular and is provided with a sealing annular flange 62c at the end opposite the grip 62 a.

The dispensing closure 60 further comprises a closure member 64 adapted to close the dispensing orifice 24b of the upper container 14. The closure member 64 is tubular.

As illustrated in fig. 13, the closure member 64 comprises a fastening element 64a designed to cooperate with a complementary fastening element provided on the inner surface of the dispensing orifice 24 b. The fastening element 64a is here a quarter turn. Alternatively, any other fastening element may be used to temporarily secure the dispensing closure 60 in the dispensing orifice 24b, such as threads, a clamping mechanism, or the like.

The closure member 64 further comprises a through hole 66 located in the vicinity of its free end, opposite the operating element 62.

The dispensing closure 60, in particular the through hole 66, serves as a collecting or sampling member for collecting or extracting a portion of the product contained in the upper container 14 or the mixture M contained in the lower container 12. The user can then test the extracted portion before using the entire product.

Thus, there is no need to add a different collecting member or to test the product with a cotton swab before the first use.

The embodiment shown in figure 14 (in which like elements have like reference numerals) differs from the embodiment of figure 13 only in the shape of the sampling member of the dispensing closure.

As illustrated in fig. 14, the dispensing closure 70 includes an operating element 72 having a grip 72a and a body 72b extending from the grip 72 a. As illustrated, the body 72b is tubular and is provided with a sealing annular flange 72c at an end opposite the grip 72 a.

The dispensing closure 70 further comprises a closure member 74 adapted to close the dispensing orifice 24b of the upper container 14. The closure member 74 is tubular.

As illustrated in fig. 14, the closure member 74 comprises a fastening element 74a designed to cooperate with a complementary fastening element provided on the inner surface of the dispensing orifice 24 b. The fastening element 74a is here a quarter turn thread. Alternatively, any other fastening element may be used to temporarily secure dispensing closure 70 in dispensing orifice 24 b.

The closure member 74 further comprises, at its free end, opposite the manoeuvring element 72, a collecting or sampling member 76 comprising a plurality of axial grooves 76a, for example regularly spaced in the circumferential direction.

The dispensing closure 70, in particular the groove 76a, allows to collect or extract a portion of the product contained in the upper container 14 or the mixture M contained in the lower container 12. The user can then test the extracted portion before using the entire product.

Thus, there is no need to add a different sampling member or to test the product with a cotton swab before the first use.

The embodiment shown in figure 15, in which like elements have like reference numerals, differs from the embodiment of figure 14 only in the shape of the collecting member of the dispensing closure.

As illustrated in fig. 15, the dispensing closure 80 includes an operating element 82 having a grip 82a and a body 82b extending from the grip 82 a. As illustrated, the body 82b is tubular and is provided with a sealing annular flange 82c at an end opposite the grip 82 a.

The dispensing closure 80 further includes a closure member 84 adapted to close the dispensing orifice 24b of the upper container 14. The closure member 84 is tubular.

As illustrated in fig. 15, the closure member 84 includes a fastening element 84a designed to mate with a complementary fastening element provided on the inner surface of the dispensing orifice 24 b. The fastening element 84a is here a quarter turn thread. Alternatively, any other fastening element may be used to temporarily secure dispensing closure 80 in dispensing orifice 24 b.

The closure member 84 further comprises, at its free end, opposite the manoeuvring element 82, a collection member 86 comprising a plurality of radial grooves 86a, for example regularly spaced axially.

The dispensing closure 80, in particular the groove 86a, allows to collect a portion of the product contained in the upper container 14 or the mixture M contained in the lower container 12. The user can then test the extracted portion before using the entire product.

Thanks to the device according to the invention, it is possible to provide a device for packaging two separate products which is simple in structure, easy to manufacture and provides a good seal between the two containers.
